Springer, 24, went 15-for-47 (.319) with three doubles, two home runs and five stolen bases in 12 Triple-A games before hitting a grand slam on Tuesday. He hit .303/.411/.600 with 37 home runs and 45 stolen bases in the minors last season, and was named the 18th best prospect in the game by Baseball America back in February.

Because he has been in the minors for a little more than two weeks, Springer's free agency has been pushed back one year. Rather than being eligible for free agency after the 2019 season, he'll have to wait until after 2020. Springer rejected a seven-year, $23 million extension over the winter, an unprecedented offer for a player who had yet to play in the big leagues.

Grossman, 24, is hitting .125/.236/.313 in the early going after putting up a .268/.332/.370 batting line in 63 games last season, his MLB debut. The 28-year-old Harrell allowed four runs in five innings on Tuesday and is now sitting on a 9.49 ERA for the year.
